Along similar lines, could you help me to understand something
about SPLOT? When I use the 'm' key in cursor mode to examine
the signal to noise, how is that number calculated? It appears
to be independent of the number of counts! In other words, I
got a SNR of 23 on a spectrum with 13,000 counts, and an SNR
of 22 on a spectrum of the same star with 1200 counts, and
that makes no sense to me.muchas gracias once again
